Bojan's place it's perfect for business or just to visit the city. The BTS (Chong Nonsi) is really close and also other interesting spots are at walking distances, like Silom Rd or Lumphini Park.
The apartment is cozy and perfect for a short or medium stay, there is an amazing gym and rooftop pool as well; great view of the CBD. Restaurants and 7/11 all around the block.
I recommend this place for your stay in Bangkok.
